Reading this thread, it feels that cleaning the language raises more problems than it solves. It is not even clear how versions should be flagged.
TC39 has worked very hard to keep the language backward compatible and avoid "breaking the web". So only a very strong motive would justify removal of features. Security is one and that explains why arguments.callee is going away, but I don't see others. Even performance isn't a strong enough motive: libraries that don't perform because of inefficient language features (with, eval) will just die or be replaced. No need to be proactive here, just let the Darwinian process take its course. Language cleanup is the business of linters. They let you enforce modern features within your teams/projects, without impacting others nor existing libraries. Derived languages and transpilers (TypeScript) are the perfect place to experiment with new features. This is much better than taking chances with JavaScript itself. If it ain't broke, don't fix it.
